排队论模型在军队医院门诊超声科设备配置中的应用

目的 探讨排队论模型在军队医院门诊超声科设备配置中的应用效果。方法 运用现场调查法和排队论模型，计算超声科设备工作强度（r），患者排队等待人数（Lq），窗口逗留人数（Ls），平均排队等待时间（Wq），平均逗留时间（Ws），设备空闲概率（P0）患者到达必须等待的概率（P）等运行指标，并对应用排队论模型配置设备前后患者及技师进行满意度调查。结果 超声科上下午分别配置6台和3台设备较为合理，在应用排队论模型配置设备后，技师和患者的满意度均得到明显提高（P＜0.05）。结论 利用排队论的方法可以较好地配置超声科设备，为提高服务效率提供科学参考。

Application of Queuing Theory in Outpatient Ultrasound Services System in a Military Hospital

Objective To discuss the effect after the application of the queuing theory model to the configuration of ultrasound equipments in the military hospital. Methods Applying the on-site investigation and queuing theory model to calculate the intensity of ultrasound service (r), the number of patients waiting in line (Lq), the number of patients stay in queuing system (Ls), the average waiting time (Wq), the average length of stay (Ws), MD idle probability (P0), and the probability of queuing when patients arrived (P), etc, and then making the satisfaction survey for physicians and patients. Results It was reasonable to configure 6 ultrasound equipments in the morning and 3 ultrasound equipments in the afternoon, and the satisfaction of physicians and patients were both improved (P <0.05). Conclusion Utilizing the theory model could be useful to provide a basis for ultrasound equipments allocation, and to provide some scientific suggestion for improving medical service efficiency.
